It’s only nine days to go until the 24 hour shoot. We shall only have about 8 hours of daylight and it doesn’t require a PhD in mathematics to work out that this means 16 hours of darkness, less a bit of twilight and a couple of blue hours. I am therefore getting into training with night shots, trying to find interesting ways of snapping the famous landmarks and keep warm at the same time. This was today’s effort on the train.
